SPECIFICATION forming part of Letters Patent No. 735,358, dated August4, 1903. Application filed February 4, 1902- Serial No. 92,595. (Nomodel.)

To all whom it mag/concern Be it known that I, ALLAN E. FRANCIS, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a new and useful Mono--gram-Type for Engraving-Machines, of which the following is aspecification.

My invention relates to improvements in the manner of forming monogramsby that class of engraving-machines in which a graver is operatedthrough the medium of a pantograph or a system of levers carrying agraver in unison with the movements of a tracer usually directed bygrooves in plates called type, and the object of my invention is toimprove the old method by which-the crosslines or filling of the lettersare cut by means of a linograph, the outlines being made by free-handtracing over printed .lines seen through a transparent and groovedlinographplate. As the character of engraved letters depends entirely onthe neatness of its outa lines, the difficulties and uncertainties ofthe old way makes it extremely hazardous to attempt cutting outlineswith machine on any thing of value, and it is to render monogramworkmore practical with machines that I have devised the following-describedmethod.

I attain the object by the type illustrated in the accompanyingdrawings, in which Figures 1, 2, and 3 show a type each from threedistinct fonts, each style being of different proportions, and the linest i represent grooves in which the point of the tracer works. Fig. 4: isa combination of the type shown in Figs. 1, 2, and 3, with an F and Tadded from the same font as Fig. 3. Fig. 5 is an enlarged sectional viewof Fig. 1 on line shown smaller figures.

at c c, and M represent grooves for directing the point of the tracer.Fig. 6 is an enlarged view of the upper part of Fig. 1, more fullyshowing the grooves for directing the point of the tracer than can beeasily done in the Fig. 7 is an enlarged fiveletter monogram as cut fromthe five type entwined as in Fig. 4.

Engraving-machine type as formerly made consist of plates of metalhaving a letter en grayed on each or plates cast from a matrix in Fig. 7is enlarged.

- give the required stability to the type. Thin stuff-such as sheetmetal, celluloid, or composition in sheets-can be cut, stamped, 0r

pressed into the shape required for difierent styles and forms ofletters and the letters can then be cut out as near the outlining-grooveas possible. In block letters of heavy proportions this would be to thevery edge of the outlining-groove but in script letters, where a singlegroove forms the body of the letter, enough of the plate must be left oneach side to give the necessary strength to the type, but not enough toseriously interfere with suitably entwining the letters.

7 Fig. 4 shows five type entwined for a monogram signifying the Francistype-entwining system. The type are fastened to a soft-wood board withthumb-tacks. These tacks may be freely used and are moved from place toplace as the tracing progresses, so that each line in a type can betraced uninterruptedly. The, board is secured to the type-table of themachine either by a flange such as holds the machine-type or it may beput downwith special screws. The type here shown are reduced in size,while the monogram as shown It will be seen that this arrangement willhelp the operator who lacks ability to design monograms, for however thetype are laid correct tracing of the disappearing parts of letters mustensue from a disappearance of the type at that point. Besides, such typeprovide an outline-groove practically for the entire monogram, reducingthe risk in cutting monograms with a machine to that of cutting otherletters.
